COLLAPSIBLE CAMP-BED FRAME.

.Application led December 28, 1920. Serial No. 433,685.

To all whom t may concern:

Be it known that we, FRANKLIN A. MILLER and BERTRAND M. TANNER,'citizens of the United States of America, residing at St. Anthony, vented certain new and useful Improvements in Collapsible Camp-Bed Frames, of which the following is a specification, reference being had therein to the accompanying drawin s.

gThe object of the present invention is to provide a foldable and collapsible campbed framev which will be strong and rigid whenf set up but which may be quickly collapsed and folded into a bundle of very small compass if desired. a u

It is a further object of the invention to provide a bed of the character .indicated of such a nature that the usual wire or canvas bed bottom or spring mattress may be employed in conjunction therewith. It is a further object of the invention to provide a bed frame of the character indicated the main portions of which are constructed of angle iron and in such a manner that the structure asa whole may be very economically manufactured. i

F urther objects and advantages of the 1nvention will be set forth in the detailed description which follows. u

In the accompanying drawings:

Figure 1 is a plan view of the hinge construction between'the side and end frame 'members of the bed;

F ig. 2 is a side elevation of the structure shown in Fig. 1;

Fig. 3 is a plan view upon a smaller scale lillustrating the overlapping portions of the side frame members;

Fig. 4 is a side elevation of the structure shown in Fig. 3;

Fig. 5 is an enlarged plan view of the overlapping portions of the side frame members; ig. 6 is a side elevation of the structure shown in Fig; 5;` and A Fig. 7 is an underside view of one of the ends of the frame membersl illustrating a truss construction hereinafter described.

Specication of Letters Patent.

arable angle bars 5 and 6 and Fremont county, Idaho, have inwhich the section 6 of carries a stud 8 that is provided with a head Patented Dec. 6, 1921.

struction is duplicated at all four corners of the bed frame. Each of the side frame members or rails B comprises two completely sepwhen these sections are longitudinally separated from each other, they may swing upon the hinge joints over into parallelism with and against the end members A. Thereafter the legs C may be folded upwardly against the under sides of said end members A and these three parts may be rolled into the wire or canvas bed bottom to constitute a compact bundle, capable of ready transportation and particularly useful for campers, automobiliste and the like.

The joints between the sections 5 and 6 of the side rails are constructed as follows The vertical flange 7 of theJtangle iron of the rail is constructed 9, the latter being offset from the vertical flange 7 a sufficient distance to permit of the notched end 10 of the vertical flange 11 of the sectionV 5 being inserted between the head 9 and the flange 7. The horizontal flange 12 of the section 6 is cut as indicated at 13 and this cut portion isv downturned to form al lug 14 which enters an opening 15 formed in the horizontal flange 16 ofthe section 5. By inserting the notched end 10 of the section 5 behind the head 9 of the stud 8 while the sections 5 and .6 are held at an angle with `relation to each other and then rocking these two sections downwardly to force the lug 14 into the opening 15. the two sections are securely united against either longitudinal or lateral separation except under the influence of an upward pull by the person who desires to collapse the frame.

The hinge joints at the corners of the bed frame are' constructed as follows: The sections 5 and 6 have hinge yokes 17 welded thereto the upper. and lower portions of which lie above and below the eyes 1 8 of hinge plates 19, said hinge plates being welded or otherwise secured toy the members A. To further aid in vsecuring the hinge plates 19 rigidly to the members A'angle clips 20 have their horizontal portions 21 welded to the under faces of the horizontal flanges 22 of the angles constituting the members A and have their vertical portions 23 welded to the inner faces of the hinged plates 19.

- The legs C are pivoted to swing about a l i imparting vertical ange stud 24. The `pivot connection between the side rails and the end members A is constituted by a 'bolt 25 which traverses the upper and lower members of the hinge yoke- 17 and the eye 1 8. The'horizontal flanges 22 of the end frame members A are provided with holes 26 in which a wire bed bottom 27 of any conventional form is engaged. 4

In setting up the bed the legs are first brought to an upright position and the side rail sections are then swung outwardly to the position illustrated in Fig. 3. At this time the vertical wall of the hinge yoke 17 will lie flat against the outer faces of the legs and thus will hold the legs securely against collapsing. Further rigidity is irnparted to thestructure by havin the lower horizontal members 2 8 of the Iiinge yoke engage in notches 29 formed inthe forward edges of the legs Whenv the legs C are brought to vertical position they are rendered additionally rigid by clips 19a secured to the outer faces of the hinge plates 19. The meeting ends of the side rail sections may then be united in the manner hereinbefore set forth and the parts will be so proportioned that the act of springing the side rail sections 5 and 6 into parallelism with each other to cause the lug 14 to enter the opening 15 will place the bed bottom fabric 27 under tension.

From the foregoing description it will be seen that a simple and inexpensive construction is herein provided by virtue of which campers, automobilists and the like are not only provided with a bed which may be easily and quicklg7 be in danger o collapsing but, 4which is equally as important, they will be provided with a bed which is as comfortable as the average permanently constructed bed. There are many camp beds on the market and many of them can be very quickly set up -but the most of them are so flimsily constructed that they are incapable of pro- Y viding a comfortable nights rest for theV user.

In Fig. 7 we have illustrated means for additional rigidity and strength to the end members A. In this 'figure a truss rod 30 has its ends enga d with the of the member The central portion of on a short pipe section or boss y31 welded to set up and which will not two pairs are this truss rod has a bearingthe underface of the horizontal flange of the member A.y

It is to be understood that the invention is not limited to the precise construction set forth but that it includes within its purview whatever changes fairly come within either the terms or the spirit of the appended claims.

Having described our invention, what we claim iS:

1. A bed bottom comprising a pair of completely separable sections, each having a transversely extending end frame member and a pair of longitudinally extending side rails, studs carried by the side rails of one pair, notches formed in the ends of the side rails of the other pair adapted to engage said studs, horizontally overlapping portions upon the side rails of the' opposed pairs which limit downward rocking movement of the two sections to a position where the side rails lie in substantial alinement with each other, legs pivotally connected to the end members and adapted to fold upwardly therebeneath and in parallelism therewith and hinge connections, between the end frame members and the side rails for permitting lthe side rails to fold in parallelism with the end frame members, portions of said hinge connections overlying and `abutting against the legs when the parts are in assembled relation to thereby hold said legs against movement.

2. A bed bottom comprlsing a pair of completely separable sections each having a transversely extending end frame member and a pair of longitudinally extending side rails, studs carried by the side rails of one pair, notches formed in the ends of the side rails of the other pair adapted to engage said studs, downwardly projecting lugs upon the ends o f the side rails of the one pair and openings formed in the horizontal'po'rtions of the side rails of the other pair into which said lugs project Iwhen the side rails of the brought substantially into horizontal alinement with each other4 and a spring bed bottom the endsof which are connected to the transverse end members.

In testimony whereof we hereunto affix our signatures.
